Cryptocurrency is a type of Digital Currency whose internal units of account are provided by a decentralized payment system (no internal or external administrator or other administrator) and its analogue operates in a fully automatic mode. The cryptocurrency itself does not have any special physical or electronic form - it is simply a number indicating the amount of these units of account recorded in the corresponding position of the data packet of the data transfer protocol, and often, even unencrypted, as well as all other information about operations between system addresses. As the Internet developed, people began to pay money "remotely". It is impossible to give money from hand to hand. Therefore, it is necessary to turn to "middleman", that is, electronic payment systems, banks or couriers. Any "partner" will be paid for the practice he performs, because no one wants to work for free. The more money you transfer, the more you lose in taxes. As information technology developed, people wondered: "how to reduce costs and run a business with a 100% increase in FIK?". There were many offers, but all were rejected, after all, even after removing the transaction taxes, how can you protect yourself from fraudsters - how can you prove that it was you who transferred or received the money? The solution was found in 2009 when Satoshi Nakamoto released a new payment system based on mathematical calculations. The currency used for payment was bitcoins. They are stored in special wallets and can be downloaded and used in another wallet. "Bitcoin" is virtual money that has no material equivalent and is simply a collection of records in a database. In order to determine whether money has been sent or received from a Bitcoin wallet account, experts have suggested publicly showing how many bitcoins have been sent and received from one wallet or another address. That is, when you connect to the cryptocurrency network, you will be able to see all Bitcoin transactions. Also, all wallets are anonymous (they don't tell you who owns them), so you'll never know if someone doesn't tell you they own a wallet. 3 24 International scientific journal ISSN: 2181-3906 «MODERN SCIENCE АND RESEARCH» 2023 VOLUME 2 / ISSUE 6 / UIF:8.2 / MODERNSCIENCE.UZ In general, "Bitcoin" is virtual money that has no material equivalent and is simply a collection of records in a database. Because both the base and the technology on it are so reliable, it could be of great value to humanity. Cryptocurrencies are created on the basis of the base called "BlockChain". We will try to explain how it works: • The basis of the idea is to create a decentralized database (which does not have a main server like bittorrent) and store copies of the data encrypted on the server of all participants of the system. In Bitcoin, it is the transaction base of all operations performed in cryptocurrency units. All registered and this information is available to all participants; • All new data in the database correspond to existing copies of the participants. Synchronization and consensus building algorithms work. In order to steal it, it is necessary to change the data of at least half of the participants, which is almost impossible to do in millions of networks; • In order to use a fake payment system, it is necessary to change the distributed databases stored in the block chain (thousands of computers), and for this it is necessary to have access to all computers. • But technology is technology and money is money. Materially available. Certain rules were adopted when creating the cryptocurrency called "Bitcoin": 1. In order to avoid strong inflation, «Bitcoin» was originally intended to limit the amount of these virtual money. Therefore, the concept of virtual gold equivalent was introduced, which can be acquired by buying or mining. The method of obtaining new "Bitcoins" is called "Mining" ("virtual miners", but they work on their own computers and specially designed systems, not with the help of picks). 2. To make "Bitcoin" more similar to gold, acquiring it has been made as difficult as mining for gold. Otherwise, new units will be added to the existing chart of the cryptocurrency. For this, all miners ("virtual miners") perform very complex calculations using their computers or a special system - they throw the calculated numbers into the given te
